NSD-1202

Overview

The NSD-1202 is a dual piezo motor driver integrated circuit manufactured by ams-OSRAM USA INC. Designed for SQL series applications, this CMOS device features an I²C interface for control. It supports output voltages ranging from 24 V to 40 V and provides four distinct outputs. The component integrates fully functional control and power stages, delivering an output current of 25 mA per channel. Packaged in a compact 16-QFN (4x4) format, it facilitates surface-mount installation.

Feature Summary

• Dual-channel architecture specifically engineered for driving piezoelectric motors within the SQL series ecosystem.
• Fully integrated design combining digital control logic with high-voltage power stages to minimize external component count.
• Digital connectivity via I²C interface enables precise configuration and monitoring through standard communication protocols.

Applications

• Piezoelectric motor actuation systems
• Precision positioning mechanisms requiring SQL series compatibility
• Automated optical or mechanical adjustment modules

Procurement Notes

Verify the specific manufacturer designation when sourcing, as documentation references both ams AG and ams-OSRAM USA INC. Confirm that the required package variant matches the 16-QFN (4x4) specification. Ensure the application voltage range aligns with the 24 V to 40 V operational limits defined for the power stage. Cross-reference part numbers carefully to distinguish between the base IC and associated accessory kits like the ASST variant.

Selection Notes

Select this component when designing circuits requiring dedicated control for dual piezo actuators. The integrated nature of the driver reduces board space requirements compared to discrete solutions. Consider the I²C interface constraints regarding bus speed and addressability. Evaluate the 25 mA output capability against the specific current demands of the target piezo motor load to ensure reliable operation without thermal overload.

Part Context

This driver belongs to the specialized family of motion control components developed for precision electromechanical applications. It complements ams-OSRAM's portfolio of sensor and actuator solutions by providing the necessary drive electronics for piezoelectric technologies. The integration reflects a trend toward miniaturized, digitally controlled motion systems in industrial and consumer devices.

Replacement Considerations

Public confirmed substitute part number: NSD-1202-ASST. This variant serves as a related offering within the same product line, potentially including additional accessories or packaging configurations. Verify functional equivalence before substitution.
